Charged tracks with \(p_{\rm T}>\)  0.15 GeV/\(c\)  within a pseudorapidity range \(|\eta |<\)  0.9 over the full azimuth are accepted. Charged-particle jets are reconstructed from the selected tracks using anti-\(k_{\rm T}\)  jet finding algorithm [1]} with the \(p_{\rm T}\) -recombination scheme of FastJet package [2]} with jet resolution parameter, \(R\)  = 0.4. Only leading jets (jet of highest \(p_{\rm T}\)  in an event) with 10 \(<p_{\rm T, jet}^{\rm ch}<\)  100 GeV/c are considered for this analysis. The mean charged particle multiplicity in leading jet (\(\langle N_{\rm ch} \rangle \) ) and leading-jet fragmentation function (\(z^{\rm ch}=p_{\rm T, track}/p_{\rm T,jet}^{\rm ch}\) , where \(p_{\rm T, track}\)  is the \(p_{\rm T}\)  of jet constituent inside the leading-jet cone) are studied as a function of jet \(p_{\rm T}\) .
